This invention relates to concrete construe t1on,and is particularly concerned with the formation. of reinforced concrete grave vaults. The apparatus shown is. for formingthe body of a top seal vault and it isto be of a bottom seal grave vault as'well.

The primary object ofthe invention is to;

provide a cheaply made and simple appae ratus for forming a substantially rectangular open container of conc'retep The apparatus,

is in the nature of a mould madein separate sections which may be easily, assembledba forepouring the concrete? with a minimum amountof labor andas easily removed from Another object 1s to provide fasteningmeans to secure the variousparts of a mould".-

but in so doingbringsthe variou's abutting edges of separate members together a ca'niming action to eliminate "so calledfins 22 on Fig. 1; Fig. 3 is the transverse cross-' section as indicated by the line 3-3- on Fig. 1;,Fig. 4 is'a fragmentary detail of a'corner of one of the molds at the separatingpoint of a'pair of moldmembers; Fig. 5 is a frag mentary. cross-section through the corner members of both the inner and outerl molds as indicated by the lines 55 on Fig i; Fig. 6 is a cross-section (similar to Fig.5) of a portion of the outsidemolds showing the manner of clamping andsecuring the separate mold'members together.

. ,My apparatus consists generally 1 of; an

inner member having sideandend' walls and a roof portion whichniay'be easily and ac; curately positionedlupon'a pouring baseol slabf The roof portion thereof'whi'ch I'ishow is naadein two {or morelsections -whichija're r siiri-ply placed on the' assembled'side and'end walls prior to; pouring the concrete. "The mermaid members consist of separatel-yIremovable side andv end walls, also positioned 'by' the pa e, a the "he ght of "the wallsibeing greater than those ofthe corresponding inner mold by substantially the desired thickness I 'prefer to makethe concrete receptacle up-v side downwhereby the inner mold members maybe assembled as an inverted box and whereby the whole area of the bottom'is' tobe utilized as, a pouring opening. To remove the mold members, I-inv-ert the vault or-containerf together with the mold, preferably by m-ea nsof trunnions mounted on the exterior mold. 'and'while" elevated transport the mold to'its proper storageispace' by a traclgway and hoist, and remove. the. a i s m ld? members, leaving the vaultright sideup.

constructed, theplate forming the mold sur-,

face .being shown as reinforced by angle members 19, the upper-oneof whichsupe J ports the edgesof the roof :members. The

intermediate angleinembers 19 on either side are shown as perforated and subtended by hooked bars 20 which serve to prevent the weight of the concrete poured into the space betweenthe outer and inner mold'members from bulging the plate inwardly, The

weight of thesebars serves to holdthemfin place while pouring the conoreteand later to. remove them when the completed vault is overturned as will be later described.

The members forming the 'outer mold are similarly'constructed except that the corresponding rein-forcing angles; are designated 21 for theend membersee-and 2'3, aria-25 fdr he s d plate 26. 1

The an le member 27 is, arovided' with rigidly attached studs which may be welded or pinned in place and which are adapted to enter elongated perforations 31 in the'member 29. The perforations 31 are elongated to facilitate assembly and each has an outwardly facing conical surface at one end thereof indicated'at 33. Thestuds 30 are adapted to receive wing nuts 35, the nut in that it is ver- 'likel to arevent the eas i'einovalof the niold members after the con crete is set. Another advantage of the con;

struction of jhe securing means isthat the life thereof is considerablyprolonged, even beveled surfaces 38. 4C

a great amount of wear on the conical "surfaces being innnaterial. V 1

The inner mold members 5 and 7 are similarly joined by angles?" and plate members QS -and 29?, an outer surface of the angle 27" being of course the molding surface and which is therefor provided with a slight draft as'contrasted with the inner surface of the angle members 27. As shown in-Fig. 2 the inner corne sof the anglemenn hers 27 are providedwithinserts 3? which terminate at their upper and lower ends in The purpose of. these inserts is to provide-a partially beveled 'off corner'to the vault to be formed whereby the necessity for handles on the vault is obviated. The manner in which these beveledoff corners serve to facilitate handling the vault is set forth in my copending apphcation Serial No. 7&9 636 filed November 13 Preparatory to setting up the mold members, a 'block'or molding slab designated 40 and shownfinl igs 2 and 3 is carefully cleaned of any accun'iulated fragments of concrete or other foreign matter. In setting up the mold the end walls?) and 6 are first placed against theinne'rline" of ribs t1 being retained in upright position bythe flanges of the angles 27 -The sidewall members are'then'located by the ribs and swunginto place with the studs projecting throughthe openings '31. ;The wing nuts 35 are-then appliedand tightened up as previously described. I

H'At this point I may use this assembled box-like structure to form a substantially continuous reinforcing member resembling a basket to be later described.. {lhe entire 29 and 27 are exterior surface of theinner mold member is then covered with oil to prevent the mold outer and inner surfaces of the assembled mold members 1 and 2 respectively is then filled with concrete, (the reinforcing member having been previously placed in the cavity),and a substantiallyflat bottom for the vault to be formed isobtained by brushing otf .the surplus' c-oncrete'even with the upperbrim of the-mold member 2 and smoothingoif the surface-with leveling trowel'or'fioat'. 7

After the concerts has set the whole mold may be raise dqby means of trunnions '50, supported as ,shown'in Fig. l by the end members 22 and 23 and carried to storing position by suitable hoisting mechanism 'en gaging the trunnions. The mold is there overturned and deposited. All the mold men'ibers may then be taken oil.

The'above described apparatus may be effectively used in forming any size and. shape of receptacle as well as a rectangular vaultand it will be'seen that the membersforming the vault may be very easilyand 'cheaply made and rapidly put together to form a complete mold and easily and. quickly removed from the finished product,- 'lhesequcnce of operation for assembling molds provides for putting in place the members which will stand'of themselves, and hence no auxiliary apparatus may be provided for this purpose nor unnecessary labor needed. in iii-airing concrete va Elt$ it is essentialthat there be no variations in the shape and size of thebrim of'thevault.
